I have notice that the Stability gets lost when I open web browsers such as mozilla or chromium . I managged to overcome this "frozening" by pressing alt+ F2 (altough I cannot log in in the console) Also by pressing Alt + F7. Only by pressing F7 alone I got the system back. Would it be a lack of memory? i have 4 GB

Your memory is sufficient but I have had bad experience of MSI motherboard with WinXP regarding USB ports. You did not install the unstable microcode for Intel processors for Meltdown did you?

I don't recall. How do I check that?
In the box from "additional drivers" I don't see anything available.

Ps: I also experience this when opening the menu in the browser

I was thinking of this thread when I posted:

viewtopic.php?f=5&t=12526&hilit=+microcode

but that relates to Core!
